According to Turner [1], it has been estimated that one third of the world's economy is generated through projects. The tangible benefits of projects may include increasing sales, improved profit margins and cash flows through increased revenue or reduced costs are amongst these. Intangible benefits might include areas of safety, improving customer service, relationships with stakeholders, and organisational capability [2]. Despite the benefits gained from projects, the Standish Groups' 2015 Chaos Report [3] measured project success for information technology project sand found that success rates of these projects are below 50% and continue to be a problem. As a result, the group's definition of a successful project was redefined to include a measure of perceived value by the customer in addition to the triple constraint of delivering on time, within budget and to the required scope. By adding perceived value, project success rates dropped further by 7%.
